In the field of electronics and optoelectronics, light-sensitive devices play a crucial role in converting light signals into electrical signals. Among the most widely used light sensors are the Photodiode, Phototransistor, and Photoresistor (also known as Light Dependent Resistor or LDR). Though they all respond to light, their construction, working principles, advantages, disadvantages, and applications […]
Diodes
In this blog we will be discussing about different types of diode and symbol. A diode is basically two terminal electronic device which allows current to flow in one direction while it blocks the current in other direction.
It is made of two types of semiconductor materials namely p-type and n-type. By varying the properties of these materials different types of of diode are manufactured. Here are some different type of diodes described as follow.
Schottky diode
PN junction diode
Avalanche diode
Zener diode
Light Emitting Diode
Photodiode
Laser diode
